A Generalized Correction for Attenuation.
Petersen, Anne C.; Bock, R. Darrell
Use of the usual bivariate correction for attenuation with more than two variables presents two statistical problems. This pairwise method may produce a covariance matrix which is not at least positive semi-definite, and the bivariate procedure does not consider the possible influences of correlated errors among the variables. The method described here, a generalized correction for attentuation, is a multivariate method which accommodates both the negative variance component problem and the collinearity problem.
